Also we introducing you ‘Introduction to the Enterprise Unified Process (EUP)’, the whitepaper summarized the book The Enterprise Unified Process: Extending the Rational Unified Process, published by Prentice Hall PTR, February 2005.

“Your organization likely has several software projects that it’s currently managing. You likely have some systems that you are currently operating and supporting in production. The actual focus of most organizations isn’t on the development of a single project, it’s on the development, operation, support, and maintenance of a collection of systems”, says Scott W. Ambler.

The often case is when you have the software that are in production and you have an active development phase.

“This implies that processes for operations, support, and maintenance efforts need to be added to the RUP. Second, to be sufficient for today’s organizations the RUP also needs to add support for the management of a portfolio of projects, something other processes have called programme, multi-project, infrastructure management, or enterprise management”. So at the picture below you can see ‘The enhanced lifecycle for the Enterprise Unified Process (EUP)’:
